BlackBerry PlayBook Updated to OS and!?

I noticed that the BlackBerry PlayBook had been updated again over the weekend to v1.0.1.1746 after doing some research i found out that .1758 was also available for download. Now that being said we are hearing that some can install both updateds and some are not seeing them at all. It seems as though RIM is slowly pushing them out to everyone. The last official OS update was to OS v1.0.1.1705. Please let us know what you find when you go to update your PlayBook.
